The document discusses RFID (radio frequency identification), which uses radio waves to electronically identify objects. It describes the basic components of an RFID system including RFID tags containing chips and antennas, readers, and application software. It also discusses the different types of RFID tags and their typical read ranges and data speeds. Examples of RFID applications mentioned include payment cards, electronic toll collection, access control, and supply chain/logistics.

3.  RFID = Radio Frequency Identification
 Electronic labeling and wireless identification of objects using radio
frequency
 Tag carries with its information
 a serial number
 Model number
 Color or any other imaginable data
 When these tags pass through a field generated by a compatible
reader, they transmit this information back to the reader, thereby
identifying the object

4.  A basic RFID system consists of these components:
 A programmable RFID tag/inlay for storing item data;
 Consisting of an RFID chip for data storage
 an antenna to facilitate communication with the RFID chip
 A reader/antenna system to interrogate the RFID inlay
 Application software and a host computer system

5.  The RFID tag consists of an integrated circuit (IC) embedded in a
thin film medium.
 Information stored in the memory of the RFID chip is transmitted
by the antenna circuit embedded in the RFID inlay via radio
frequencies, to an RFID reader
 3 types
 Passive
 Semi-passive
 Active

6. Active Tags
•Use a battery
•communicate over
distances of several
meters
Semi-passive Tags
•Contain built-in
batteries to power the
chip’s circuitry, resist
interference and
circumvent a lack of
power from the reader
signal due to long
distance.
•They are different from
active tags in that they
only transmit data at the
time a response is
received
Passive Tags
•Derive their power from
the field generated by
the reader
•without having an active
transmitter to transfer
the information stored

15.  Positive
 RFID is a contactless reading technology and can
read through other materials
 Hold more data than barcode does
 RFID tags data can be changed or added
 More effective, bring lots of convenience to us
 Negative
 Cost is relatively remain high (compare to barcode)
 RFID signals may have problems with some
materials
 RFID standards are still being developed
